Abstract
Description
-
- the communication originating node is identified by a fixed address and a variable address, and said update request further contains said fixed address and an assigned variable address;
- said routing node acknowledges receipt of the submitted request verification information;
- said verification request and said retrieving (5.) are secured by a random challenge;
- said request verification information is generated by applying a cryptographic function on said update request;
- said cryptographic function is a Hash-function;
- said request verification information is generated by applying a cryptographic function on said fixed address and said assigned variable address contained in said update request;
- said cryptographic function is a Hash-function;
- the method further comprises the steps of generating at the communication partner node said request verification information based on the received routing entry update, comparing the generated request verification information with said retrieved request verification information, and updating the routing entry in case the comparison yields that the generated request verification information and said retrieved request verification information are identical;
- said request verification information is generated by applying a cryptographic function on said update request;
- said cryptographic function is a Hash-function.
